A Parsing Scheme for Finding the Design Pattern and Reducing the Development Cost of Reusable Object Oriented Software
Because of the importance of object oriented methodologies, the research in
developing new measure for object oriented system development is getting
increased focus. The most of the metrics need to find the interactions between
the objects and modules for developing necessary metric and an influential
software measure that is attracting the software developers, designers and
researchers. In this paper a new interactions are defined for object oriented
system. Using these interactions, a parser is developed to analyze the existing
architecture of the software. Within the design model, it is necessary for
design classes to collaborate with one another. However, collaboration should
be kept to an acceptable minimum i.e. better designing practice will introduce
low coupling. If a design model is highly coupled, the system is difficult to
implement, to test and to maintain overtime. In case of enhancing software, we
need to introduce or remove module and in that case coupling is the most
important factor to be considered because unnecessary coupling may make the
system unstable and may cause reduction in the system's performance. So
coupling is thought to be a desirable goal in software construction, leading to
better values for external software qualities such as maintainability,
reusability and so on. To test this hypothesis, a good measure of class
coupling is needed. In this paper, based on the developed tool called Design
Analyzer we propose a methodology to reuse an existing system with the
objective of enhancing an existing Object oriented system keeping the coupling
as low as possible.Comment: 15 page
Brain image clustering by wavelet energy and CBSSO optimization algorithm
Previously, the diagnosis of brain abnormality was significantly important in the saving of social and hospital resources. Wavelet energy is known as an effective feature detection which has great efficiency in different utilities. This paper suggests a new method based on wavelet energy to automatically classify magnetic resonance imaging (MRI) brain images into two groups (normal and abnormal), utilizing support vector machine (SVM) classification based on chaotic binary shark smell optimization (CBSSO) to optimize the SVM weights.
The results of the suggested CBSSO-based KSVM are compared favorably to several other methods in terms of better sensitivity and authenticity. The proposed CAD system can additionally be utilized to categorize the images with various pathological conditions, types, and illness modes
Does credit improve the food consumption vulnerability of the extreme poor? - Empirical evidence from Bangladesh
This paper examines the extent of seasonal hunger and its food consumption vulnerability among rural households in the North West part of Bangladesh (i.e., the greater Rangpur region) and whether the Programmed Initiative for Monga Eradication or PRIME interventions (such as flexible micro-credit, Emergency loan and cash for work) have some positive impact for improving the consumption ordering of monga affected households or not. Seasonal hunger, also known as monga in greater Rangpur, is caused by a deprivation of food during certain months of the year when households do not have adequate employment, income, and savings. That is, monga is an ex post measure of seasonal deprivation of food. However, for policymaking purpose, knowing who are going to be in seasonal hunger in future is more important than knowing who already are. This ex post measure of seasonal food deprivation through the changes in consumption ordering in two years- 2008 and 2007 can be defined as food consumption vulnerability. That is, vulnerability to seasonal hunger is the likelihood of remaining in or falling into seasonal hunger. Households smooth consumption via income smoothing and other measures, which also reduce their vulnerability to monga. When consumption smoothing does not happen for one reason or another, food deprivation is sure to follow.Poverty, Microfinance, Impact Analysis, Food Consumption Vulnerability,
Optical wave evolution due to interaction with elastic wave in a phoxonic crystal slab waveguide
Phoxonic crystal as a means of guiding and confining electromagnetic and
elastic waves has already attracted attentions. Lack of exact knowledge on how
these two types of waves interact inside this crystal and how electromagnetic
wave evolves through this interaction has increased this field complexity. Here
we explain how an elastic wave affects an electromagnetic wave through
photo-elasticity and interface displacement mechanisms in a phoxonic crystal
slab waveguide. We obtain a master equation which can describe electromagnetic
wave evolution. In this equation we define a coupling parameter and calculate
its value for different modes of electromagnetic and elastic waves and show it
vanishes for some types of modes . Finally we solve the master equation for a
typical phoxonic crystal slab waveguide and illustrate the electromagnetic wave
evolution
